MediciNova Announces Publication of Positive Findings from Completed Phase 1b Clinical Trial of MN-166 (ibudilast) in Methamphetamine Dependence

LA JOLLA, Calif., March 30, 2016 (GLOBE NEWSWIRE) -- MediciNova, Inc., a biopharmaceutical company traded on the NASDAQ Global Market (NASDAQ:MNOV) and the JASDAQ Market of the Tokyo Stock Exchange (Code Number: 4875), today announced that the medical journal Drug and Alcohol Dependence has published a new article regarding positive findings from a completed Phase 1b clinical trial of MN-166 (ibudilast) in methamphetamine dependence. The article, which was written by Matthew J. Worley, Keith G. Heinzerling, and colleagues at the University of California, Los Angeles (UCLA), reports that MN-166 (ibudilast) was shown to significantly reduce the subjective effects of methamphetamine in subjects diagnosed with methamphetamine dependence.

Major findings from the publication, “Ibudilast attenuates subjective effects of methamphetamine in a placebo-controlled inpatient study,” include the following:

  • MN-166 significantly reduced the prototypical subjective effects of methamphetamine, such as “high” (How high are you?) (p<0.01), “effect” (Any drug effect?) (p<0.001), and “good” (Any good effects?) (p<0.05);
  • MN-166 also showed a reduction in subjective effects such as “stimulated” (How stimulated do you feel?) and “like” (How much do you like the drug?).

Yuichi Iwaki, MD, PhD, President and Chief Executive Officer of MediciNova, Inc., commented, "We are very pleased that the detailed results of the first clinical trial evaluating MN-166 in methamphetamine-dependent subjects have been published. Based on the reported positive findings from this study, we continue to work in collaboration with researchers at UCLA on a much larger ongoing Phase 2 clinical study to evaluate MN-166 in methamphetamine-dependent subjects."

About the Ongoing Clinical Trial

The study is a randomized, placebo-controlled, double-blind, outpatient Phase 2 study of MN-166 (ibudilast) in treatment-seeking methamphetamine-dependent subjects (n=140). Eligible participants are randomized, stratified by HIV serostatus, to ibudilast 50 mg twice a day or placebo treatment for 12 weeks, with twice weekly clinic visits for counseling, urine drug tests, and safety/medication adherence monitoring. The study is designed to detect a statistically significant benefit of MN-166 over placebo on the primary study outcome of methamphetamine abstinence during the final two weeks of treatment.

About MN-166 (ibudilast)

MN-166 (ibudilast) has been marketed in Japan and Korea since 1989 to treat post-stroke complications and bronchial asthma. MediciNova licensed MN-166 (ibudilast) from Kyorin Pharmaceutical Co., Ltd. for potential utility in RRMS. Intellectual property was additionally established or obtained by MediciNova in progressive MS and other neurological conditions. MN-166 (ibudilast) is a first-in-class, orally bioavailable, small molecule phosphodiesterase (PDE) -4 and -10 inhibitor and a macrophage migration inhibitory factor (MIF) inhibitor that suppresses pro-inflammatory cytokines and promotes neurotrophic factors. It attenuates activated glia cells, which play a major role in certain neurological conditions. Ibudilast's anti-neuroinflammatory and neuroprotective actions have been demonstrated in preclinical and clinical study results and provide the rationale for its therapeutic utility in neurodegenerative diseases (e.g., progressive MS and amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig’s disease), substance abuse/addiction and chronic neuropathic pain.
